the most terrible anime you've ever watched

Twelve Kingdoms. I've been bitching about this on another thread because it was excruciating to watch but I couldn't stop. Now it's over and I can say in full force it was terrible. It started story lines carried from the manga which were not relevant at all to the main story. That would be fine and dandy but it cut off those story lines and never wrapped them up in the end. A forth of the series was dedicated to a character that was never mentioned in the last half of the series. WHY? To sell the manga?

im probably gonna get hated for this but naruto i have tried to watch it on sevral ocassions but its not my cup of mocha so i gave it a chance it was not to my liking everyone has different tastes so dont be so mean i gave it a fair try

Hanayamata,couldn't make through half an episode, it was boring for a slice of life and that is really saying something.

Hmm - I'd have to say Elfen Lied. Really couldn't get into the anime, too much random blood and gore. I mean the girl practically looked at people and blew them apart. Meh just not my type of anime. Props to anyone else who enjoyed it though.

Samurai 7, I watched twelve episodes of it to give it a chance and see if it would get better, but it was just terrible.

Probably GI.Joe Sigma 6. It's an Anime G.I. Joe series. I watched the whole series but that's probably because I was a naive kid back then.

Naruto, DBZ, Bleach and Fairy Tail for the same reason, long, dragging story with no real plot and horribly predictable, and the characters in Naruto were just annoying.
